Learn Mandatory LaTeX with PF: A Step-by-Step Guide

  • Start date
In summary: WarrenIs it working now?- Warren\psilooks like it works; good job!- WarrenIn summary, PF is implementing LaTeX on PF with the use of a new bbcode [ tex][ /tex] or [ latex][ /latex], allowing members to use LaTeX code within the tags to display equations. Additional features include a popup window for displaying code, and the ability to use macros. However, there may be some issues with image generation and server speed.

Perhaps... I'm not sure what's hanging it up. I'm trying to figure that out now... eek.

I just looked through the lists.

Are there commands for double and triple integral as well as surface and volume integral symbols?
 
  • #41
looks like we bogged the server down, once it's fixed we'll open up testing again.

Woohoo... sorry about the mistake guys.

[tex]\gamma \equiv \frac{1}{\sqrt{1 - v^2/c^2}}[/tex]

I tried this one as an edit to a previous post, and it did not work there upon reloading.

A psi doesn't work?

[tex]\psi[/tex]
 
  • #47
What I typed up there was "\psi"; instead, I see what I would have expected afger typing "\alpha".

I guess I'll just have to wait a little longer.

okay, let's try
[itex]
$\Delta V_{(R_{1}\rightarrow R_{2})}= V_{R_{1}}\left[\sqrt{\frac{2R_{2}}{R_{1}+R_{2}}}-1 \right]$ [/itex]

Yeah something is weird...

this

[tex]
\psi
[/tex]

is different from this

[tex]\psi[/tex]

and it shouldn't be.

There we go!

The server is trying to confuse us all! :smile:

Now you see it, now you don't, now you complain, now it's ok, it looked different just a minute ago...

The reason is looks wacky is simple:

1) Some graphics take longer than others to create; they're all in background processes. Sometimes, you view the thread at first, but your graphics are not done yet.

2) When a graphic is not present (because it is not done being generated), the stupid webserver will try to help you out by sending you another graphic with a similar filename. It's supposed to help you avoid 404 errors for spelling mistakes. I really hate this "feature," because in this case, it results in your post showing someone else's graphics temporarily until yours are done!

I'm going to fix this in a few minutes.. hold on.

  • #55
Okay, let's try this. This should fix the weirdness.

[tex]
\Delta V = - I_{sp} \times g_0 \times \ln{\frac{M_L + M_i}{M_L + M_i + M_P}}
[/tex]

This stuff looks GREAT! Let's have a go at it

[tex]\int_{-\infty}^{\infty}[/tex]


[tex] \stackrel \cdot x[/tex]

[tex] \ddot{x} = -g[/tex]
[tex]\int \ddot{x}dt = \int -gdt[/tex]
[tex]\dot{x} = -gt + C[/tex]
[tex] \dot{x}(0)= V_0 \Rightarrow C = V_0[/tex]
[tex]\int \dot{x}dt = \int -gt + V_0 dt[/tex]
[tex]x(t)= - \frac {gt^2} {2} + V_0t + X_0 [/tex]


[tex]\mbox{ x=y} \mbox{\iff |x-y| < \epsilon} \forall \mbox{ \epsilon \in \Re}[/tex]

[tex]\ddot{x} = \frac {d^2x} {dt^2}[/tex]

Okay guys...

Keep playing with the LaTeX stuff.

At the moment, it seems like newreply.php sometimes doesn't work quite right, but I can't identify the situations where it fails just yet.

If you post a new reply and something doesn't work right, hit edit, then save, and it should be fine. I'm going to look into the problem soon.

In the meantime, practice LaTeX and let me know what you find.

1. What is LaTeX and why is it important for scientists?

LaTeX is a typesetting software used for creating professional-looking documents, particularly in the fields of science and mathematics. It is important for scientists because it allows for precise and consistent formatting of complex equations, tables, and figures, making it easier to communicate research findings in a clear and organized manner.

2. How can I get started with learning LaTeX?

The best way to get started with learning LaTeX is to familiarize yourself with the basic syntax and commands. There are many online resources, such as tutorials and guides, that can help you get started. You can also practice by working on small projects and gradually increasing the complexity as you become more comfortable with the software.

3. What is the difference between LaTeX and other word processing software?

Unlike other word processing software, LaTeX uses a markup language to format documents, which allows for more precise control over the layout and design. It also has built-in features for handling complex mathematical equations and referencing, making it a preferred choice for scientific writing.

4. Can I use LaTeX for collaborative writing?

Yes, LaTeX has features that allow for collaborative writing, such as version control and the ability to merge changes from multiple authors. However, it may require some additional setup and knowledge of the software's collaboration tools.

5. Is LaTeX difficult to learn?

Learning LaTeX may seem daunting at first, but with practice and patience, it can become a valuable tool for scientists. The syntax may take some time to get used to, but there are many resources available to help you along the way. As with any new skill, it takes time and practice to become proficient.
